Question

1.Sulfur dioxide reacts with chlorine at 227 oC:

SO2(g) +Cl2(g) ? SO2Cl2(g)

Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of
SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15
minutes, the concentration of SO2Cl2 is 45.5 µg/mL. You will
determine if the system has reached equilibrium.
a)First, what is Kc (in L/mol)? (A µg is 10-6 g.)
b)Next determine all initial concentrations. What is the initial
sulfur dioxide concentration (in mol/L or M)?
c)Determine all concentrations after 15 minutes. What is the
chlorine concentration?
d)Calculate the mass (in g) of SO2Cl2 expected at
equilibrium.
e)What is Q after 15 minutes?
